This study aims to develop a novel hierarchical rule-based LU extraction framework using geographic vector and remotely sensed (RS) data, in order to extract detailed subzonal LU information, residential LU in this study. The LU extraction system is developed to extract residential LU at a fine spatial level  parcel through morphological analysis. First, a novel hybrid pixel- and object-based land cover (LC) classification system, coupled with a sophisticated GIS post-classification correction process, is developed to extract land cover, including vegetation, parking lot, and bare soil, required for LU classification. The land cover classification system developed results in an overall accuracy of 96.4%. Residential LUs are then extracted by examining the morphological properties of individual parcels (which are derived from RS and geographic vector data) using a binary logistic model, which results in an overall accuracy of 97.5%. The above results show that the LU classification expert system developed can classify and then divide large zones with mixed LUs into single-LU subzones with a high accuracy. Therefore, it has a significant value to address several persistent issues caused by using large zones in urban modeling, such as intrazonal travel and mixed-LU zones.}, keywords = {Land use classification,land cover classification,Remote Sensing,morphological analysis}, url = {http://www.ijte.ir/article_3233.html}, eprint = {http://www.ijte.ir/article_3233_2a532015573d06f0414b943b43da0198.pdf} } @article { author = {Gahlot, Vimal and Swami, B.L. and Parida, M. and Kalla, P.}, title = {Availability and Accessibility Assessment of Public Transit System in Jaipur City}, journal = {International Journal of Transportation Engineering}, volume = {1}, number = {2}, pages = {81-91}, year = {2013}, publisher = {Tarrahan Parseh Transportation Research Institute}, issn = {2322-259X}, eissn = {2538-3728}, doi = {10.22119/ijte.2013.3234}, abstract = {Majority of the million plus cities in India are facing serious problems of traffic congestion and pollution due to the unprecedented and rapid pace of urbanization in last decade. City planners are providing solution to these twin problems by developing Mass Rapid Transit System including Metro and BRT in many Indian Metropolitan cities. The availability of transit network and pedestrian accessibility is key issue in planning of effective Public Transit, which affects the ridership significantly. The studies around the globe have shown that lack of accessibility and poor quality pedestrian infrastructure has led to the continued loss of mode share for public transit trips in cities. In the present study, public transit network availability and pedestrian accessibility has been estimated for the city bus routes in Jaipur city. To assess the availability of public transit network on spatial basis, some numerical index has been introduced using GIS tools, based on capacity, frequency and coverage as Public Transit Coverage Index (PTCI), similarly to measure the pedestrian accessibility numerical indices, as Ideal and Actual Stop Accessibility Index (ISAI and ASAI) and Stop Coverage Ratio Index (SCRI) has also been determined on GIS platform. These indices indicate the well served or underserved area by existing transit network and accessibility of a bus stop through the surrounding road network which may help town planners to develop future transit network and also the pedestrian facilities around a bus stop in order to make transit system more accessible and to increase the public transit mode share in the city.}, keywords = {Public transit availability,bus stop coverage,pedestrian accessibility,GIS}, url = {http://www.ijte.ir/article_3234.html}, eprint = {http://www.ijte.ir/article_3234_760af2999fb018935359adfab87d4309.pdf} } @article { author = {Hafezi, Mohammad Hesam and Shokri, Foad and Falamarzi, Amir and Ismail, Amiruddin and .K.

In such circumstances government policy would encourage people to use public transportation. In the meantime, employing the Intelligent Transport System consisting of two parts including private sector and public sector by predicting the dynamic travel time, can help the travelers to be aware of the latest traffic information. To achieve this objective, the calculation of traffic flow, demand of passenger and transport means availability are vital. The double constraint gravity model is a crucial methodology for predicting the origin destination matrix. This paper represents a Travel System Pattern (TSP) based on proposed methodology. TSP tries to let the travellers and authority know about the best travel route with considering the shortest dynamic travel time information. For this purpose the travellers are able to be aware of the travel time and other details of travel route via the internet or SMS system. Hence, a case study based on an actual public and private network in Kuala Lumpur, Malaysia is chosen as a case study area. The result shows that the accuracy of the proposed method indicated reasonable R2 of 0.926 for the evening rush traffic period. This indicates that the TSP developed in the present study is a reliable and suitable tool to guide the travellers and companies.}, keywords = {OD matrix,traffic assignment,multi-modal,ITS,delay time}, url = {http://www.ijte.ir/article_3235.html}, eprint = {http://www.ijte.ir/article_3235_93a46be5369decf3a6b8455c15ae3a92.pdf} } @article { author = {Sarvi, Majid and Sabzehali, Hassan}, title = {A Systematic Method to Analyze Transport Networks: Considering Traffic Shifts}, journal = {International Journal of Transportation Engineering}, volume = {1}, number = {2}, pages = {101-113}, year = {2013}, publisher = {Tarrahan Parseh Transportation Research Institute}, issn = {2322-259X}, eissn = {2538-3728}, doi = {10.22119/ijte.2013.3236}, abstract = {Current network modeling practices usually assess the network performance at specified time interval, i.e. every 5 or 10 years time horizon. Furthermore, they are usually based on partially predictable data, which are being generated through various stochastic procedures. In this research, a new quantitative based methodology which combines combinatorial optimization modeling and transportation network engineering has been implemented to identify the network performance over time horizon. This method incorporates both uniform traffic demand growth and demand shifts towards more attractive zones (demand uncertainty) in the network. The proposed combinatorial programming approach defines a quantitative measure of growth and shift in the traffic load that a network can sustain. This method can assess the various potential growth topology of a transport network and investigate if a specified topology can sustain more traffic demand or if any specific topology can handle traffic shifts without significant need to amend the network infrastructure. It is believed that this quantitative measure is useful both in transport network design and in the performance analysis of the existing networks. In this paper, the application of this method is demonstrated by applying the method to a part of the Melbourne’s transportation network.}, keywords = {Transportation engineering,network design and planning,transport network optimization}, url = {http://www.ijte.ir/article_3236.html}, eprint = {http://www.ijte.ir/article_3236_5b98054bce8fc116eee67890d8955d60.pdf} } @article { author = {Yaghoubi, Ehsan and Ahadi, Mohammad Reza and Alijanpour Sheshpoli, Mohsen and Jahanian Pahlevanloo, Hamid}, title = {Evaluating the Performance of Hot Mix Asphalt with Reclaimed Asphalt Pavement and Heavy Vacuum Slops as Rejuvenator}, journal = {International Journal of Transportation Engineering}, volume = {1}, number = {2}, pages = {115-124}, year = {2013}, publisher = {Tarrahan Parseh Transportation Research Institute}, issn = {2322-259X}, eissn = {2538-3728}, doi = {10.22119/ijte.2013.3237}, abstract = {Due to the high price of crude oil, and consequently asphalt binder, the application of Reclaimed Asphalt Pavement (RAP) in pavement technology is widely considered. The present paper is the result of a laboratory research which was carried out to investigate the effects of adding a rejuvenating agent to Hot Mix Asphalt (HMA) with RAP. To this end, test samples comprised of Aged Asphalt Binder (AAB) that were extracted from RAP, together with a rejuvenating agent were added in different ratios. The study made use of a variety of tests to determine the different percentage ratios of rejuvenator in terms of penetration, softening point and viscosity of the binder. The Marshall Method was then applied to investigate the impact of using a different recycling agent content on the performance of the prepared mixtures. Also, the Universal Testing Machine apparatus was used to determine the resilient modulus and dynamic creep of reclaimed asphalt. The results show that after adding 10% of Heavy Vacuum Slops (HVS) from the Tehran refinery as the rejuvenating agent to reclaim the aged asphalt, there is an improvement in the applicability of reclaimed asphalt cement. In addition, the test results suggest that adding 10% of the rejuvenator leads to RAP mixtures which meet the criteria of a virgin HMA.}, keywords = {Reclaimed Asphalt Pavement,aged asphalt binder,rejuvenator,heavy vacuum slops,Hot Mix Asphalt}, url = {http://www.ijte.ir/article_3237.html}, eprint = {http://www.ijte.ir/article_3237_10f48f58f6083f7024d44011379bdfdc.pdf} } @article { author = {Ziari, Hasan and Farahani, Hosein and Goli, Ahmad}, title = {Using the Statistical Analysis of Carbon Nano-tubes Dispersion in Bitumen Employing MINITAB Software}, journal = {International Journal of Transportation Engineering}, volume = {1}, number = {2}, pages = {125-136}, year = {2013}, publisher = {Tarrahan Parseh Transportation Research Institute}, issn = {2322-259X}, eissn = {2538-3728}, doi = {10.22119/ijte.2013.3238}, abstract = {Nowadays, utilisation of Nano-materials as one of the most recent methods of bitumen modification has attracted attention of many researchers.
